The same thing happened to me.
For me, I knew in advance that would be the likely outcome. I don’t regret it, because it had become important to me that, in the unlikely event that any other victims came forward, there would already be something on the record to support their story.
It’s different for everyone, but another one of the reasons I reported was because I wanted to treat myself like it mattered. I have no control over police processes, or justice systems. But I did have control over whether I treated myself like what happened to me was criminal. I still feel like that was an important part of my recovery - not because of how the rest of the world reacted to my reporting, but because of the impact it had on my relationship with myself.
I’m also grateful that I wasn’t put through the trauma of a trial that likely wouldn’t have been successful. That wouldn’t have been a good outcome for me.
